APPARATUS FOR DRYING OR CREMATING GARBAGE AND FECAL MATTER.

SPECIFICATION forming part of Letters Patent No. 481,147, dated August16, 1892.

Application filed September 29, 1891. Serial No. 407,185. (No model.)

To all whom it may doncern:

Be it known that 1, JOHN HAND PARKE, a citizen of the United States, anda resident of Philadelphia, Pennsylvania, have invented certainImprovements in Apparatus for Drying or Cremating Garbage and FecalMatter, of which the following is a specification.

The object of myinvention is to providean effective apparatus for thedrying or cremation of garbage, fecal matter, and offal generally, theapparatus being capable of being constructed on a large scale, althoughintended principally for domestic use, where the heat may be derivedfrom an ordinary kitchen-range or from an ordinary heating stoveorfurnace, the operation beingcarried on without the escape of anyoffensive odor into the outside atmosphere or into the air of the roomor apartment in which the apparatus is situated.

The apparatus is also especially adapted for carrying out the operationof artificial nitrification and utilization of drain-waters and wastesof farm-houses or villages situated in agricultural districts.

In the accompanying drawings, Figure l is a longitudinal sectional viewof apparatus constructed in accordance with my invention for the purposeof an odorless dry closetfor the reception of fecal matter. Fig. 2 is asectional plan view, on a reduced scale, on the line 1 2, Fig. 1. Fig. 3is a sectional plan view, on a reduced scale, on the line 3 4, Fig. 1.Fig. 4 is a longitudinal sectional view of apparatus constructed inaccordance with my invention for the purpose of destroying garbage.

In Fig. 1, A represents an outer casing, preferably of metal, having alining a of some non-conducting and heat-resisting material, whichlining is held in place by an internal framework a, bolted or otherwisesecured to the casing A.

In the front of the casing are a series of openings closed by doors B B13 which are likewise lined with non-conducting and heatresistingmaterial, held in place by an internal finger.

\Vith the casing, close to the bottom of the same, communicates a pipeD, which is in communication with the flue or chimney for the dischargeof the products of combustion from the stove, heater, or furnace, thecommunication being, by preference, of the character describedhereinafter, so that the products of combustion may be caused to passeither directly or indirectly from said stove or furnace into the casingA, from the upper portion of which they escape to the chimney or stackthrough a discharge-pipe D. The pipe D may, however, receive a supply ofhot air instead of products of combustion, although the latter arepreferred.

Mounted in the upper portion of the casing is a hopper F, and directlybeneath the same is a grating F, and beneath the latter are two pans ortrays G G,one above the other, these pans or trays being mounted uponsuitable guides in the casing, so that they can be readily withdrawnwhen necessary.

. The hopper can be constructed of wire, if

desired, and with the pan or tray permanently attached thereto, withoutdeparting from the spirit of my invention.

In the front of the casing above the upper door 13 are a series ofopenings 1), and in the rear of the casing, near the top of the same,are like openings 1), the latter communicating with an enlargement orhood D upon the discharge-pipe D.

The top H of the casing carries a hinged seat II with opening similar tothat of an ordinary water-closet, said top H having a correspondingopening formed in it. 11 is hollow, so as to form a chamber cl, withdetachable cap-plate (1, this chamber beingintended for the reception ofdisinfecting material, and the top has at the front of the seatopening adepending portion fitheinner shell of which is perforated,as at f ,forthe escape of the disinfecting-vapors into the casing A, the cap-plate dand seat H being also perforated, as shown by dotted lines in Fig. 1,for the escape of disinfecting gas or vapors into the room or apartmentcontaining the apparatus.

Hinged to the seat II is a lid or cover I, which has secured to itsunder side a box or chamber 1 for containing disinfectant, this boxfitting within the seat-opening when the lid is lowered.

The trays G G extend completely across the casing transversely, and thelower tray Thetop has a flange g extending to the rear wall of thecasing, while the upper tray has a flange 9, extending to the lining ofthe door B, a space, however, being presented between the front of thecasing and the front of the lower tray G, and between the back of thecasing and the back of the upper tray G.

Extending across the casing, between the back wall of the same and therear of the hopper F is a partition J, which also extends forward partway along each side of said hopper, as shown in Figs. 1 and 3. The fecalmatter is deposited in the hopper F, the solid por tions being retainedby the grate F, and the urine and liquid portions of said fecal matterpassing through the grating and into the upper tray G, and,if sufficientin quantity to more than fill said tray, overflowing into the lower trayG. These trays are amply sufficient in capacity to contain all of theliquid matter likely under any circumstances to accumulate in theapparatus; but in order to provide for the introduction of an excessivequantity of liquid matter into the apparatus within ashort period, suchas would cause the lower tray also to overflow, the bottom K of thecasing is dished and is provided with a valved outletpipe 7L, leading toa sewer or any convenient receptacle for such liquid matter. The heatedproducts of combustion entering the casing through the pipe D pass firstunder thelower tray G, then up at the front of the same, then rearwardabove said tray and beneath the upper tray G, then upward at the rear ofsaid tray G and forward over the top of the same and beneath the grateF, thence up in front of the hopper F and along each side of the same tothe rear, whence they escape through the outlet'pipe D, the said heatedproducts of combustion being prevented from rising around the hopperinto the space above the same, owing to the contact of the flange aroundthe upper edge of said hopper with the supporting ledge or shelf aroundthe inner shell or lining of the main casing. The products of combustionare also, by preference, prevented from gaining access to the upper doorBby means of a guard-plate M, interposed between the hopper and thelining of the casing A, this guard-plate having, by preference, at thebottom an inwardlyprojecting flange t' to deflect the products ofcombustion toward the hopper. It will be understood, therefore, that thesolid matters deposited upon the grate F and the liquid matter in thetrays G G will be subjected to such heat and will expose so much surfacethat the solid matter will be readily and thoron ghly desiccated and theliquid matters evaporated,the products of combustion rendering inodorousthe emanations from the fecal matter, and also, by reason of their heat,de-

stroying any germs of disease which might otherwise be carried into theatmosphere. Cold air enters the casing through the openings Z) near thetop and passes directly across the casing above the hopper to theopenings 1) at the rear, through which it escapes into a discharge-pipeD, and any of the heated products of combustion which find. their waythrough the grate F and through or around the solid fecal matterdeposited in the hopper F are caught by this current and carried with itinto the discharge-pipe, so as to prevent any discomfort to the occupantof the seat H.

In constructing the apparatus for use simply as a garbage or offalcremator the seat and lid shown in Fig. 1 are dispensed with, and thecasing has a plain top provided with a movable cover 11, and the hopperhas in its sides hooded openings on, so as to provide for the moreeffective drainage of the contents of said hopper as well, as for theentrance of the products of combustion into the mass contained in thehopper. In either case the tray or trays beneath the hopper provideconvenient receptacles for the chemical or carbonaceous matters intendedto be used in carrying out the process of artificial nitrification andfor fostering organisms which feed upon that portion of the refuse whichwould otherwise become offensive and dangerous. In some cases thehopperfor fecal matter and the hopper for garbage may be placed side by sidein the same casing.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. The within-described apparatus for cremating or dryinggarbage or fecal matter, the same consisting of a casing having an inletand outlet for hot air or products of combustion, a grated hopper forreceiving the garbage or fecal matter, and one or more trays or pansbeneath said hopper, said hopper and trays being interposed in the pathof the hot air or products of combustion in its passage through thecasing, substantially as specified.

2. The within-described dry closet,the same consisting of a casinghaving inlet and outlet for hot air or products of combustion, a gratedhopper contained within said casing, means for causing the hot air orproducts of combustion to circulate around said hopper, and a seatcontaining a chamber for disinfecting material, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN H. PARKE.
